This is a weird one. I changed my tranny fluid and replaced the filter about a week ago. The first time I turned on the truck the odometer started rolling forward and the speedometer started going up when I was parked. It seemed to calm down for a couple of days, but today it was acting really weird. The odometer was going forward and backwards, and the speedometer is way off. I guess if the odometer was going backwards the whole time I might not mind as much. I filled my tranny fluid a bit to high and blew it buy not putting in a cover with a drain bolt. I've been to lazy to drain some back out. Other than that, it seems to run pretty good. I was wondering if anyone had seen something like this one before.
